Just 12 months after Maddison was sold to the Foxes in a deal worth around £25m, the former Coventry City playmaker is attracting the attention of Premier League giants Manchester City and Tottenham.
Leicester have reportedly put a £60m price tag on Maddison and it is understood the Canaries would take 15 per cent of any profit made by Leicester on the deal, which would amount to between £5-6m.
Tottenham see Maddison as an ideal replacement for Christian Eriksen, who could leave the Champions League finalists this summer with just one year left on his contract. Real Madrid are apparently keen on the Danish international.
Meanwhile, Manchester City are trying to find an heir to David Silva, 33, at the Etihad with Maddison high on their list of options and manager Pep Guardiola known to be an admirer of Maddison.
